OBS Studio 29.1

If you would like to support the OBS Project, please consider contributing to our Patreon or Open Collective!

New Features

• Added support for streaming AV1/HEVC over Enhanced RTMP [YouTube/yuriy-chunak/derrod]
  • Enhanced RTMP V1 extends the RTMP protocol to support newer video codecs and HDR. More info at: https://github.com/veovera/enhanced-rtmp
  • Currently only supported by/enabled for YouTube as a beta feature
  • HDR is not yet implemented
• Added support for multiple audio tracks in Simple output recording [pkv]
• Added a DLL blocking feature for Windows. This allows OBS to block problematic DLLs from attaching to OBS and causing freezing or crashes, for example 3rd party overlay hooks and outdated video capture devices. [notr1ch]
  • This blocks old versions of popular VTubing software virtual cameras that are known to cause freezes when accessing video capture device properties. If you are affected, please update to the latest version of your VTubing software.
• Added settings to select the audio encoder for streaming and recording [tytan652]
• Added an option to preload media sources used in Stingers to memory, to avoid frame skips during transitions [Jim]
• Added Update Channels on macOS and updated Sparkle for smaller and faster updates going forward [derrod]
• Added compatibility notices in the Window and Game Capture sources for Windows [derrod]
• Added the ability to zoom browser docks with Ctrl - and + and the right click menu [WizardCM]
• Added a setting to record in fragmented MP4 and MOV formats [derrod]
  • These offer greater compatibility than MKV while providing similar resilience against data loss due to crashes, running out of space, etc.
  • Fragmented MP4 and MOV files can be remuxed to regular MP4/MOV in cases where the former may not be read correctly (e.g. in older editing software)
• Added support for surround sound for AJA capture cards [paulh-aja]
• Added ProRes 4444 (XQ) support for VideoToolbox encoder on macOS [jpark37]

• Expanded support for subtitle tracks in VLC source (up to 1000) [jjm2473]
• The Hotkeys tab in settings is no longer loaded until switched to, resulting in the Settings window opening much faster for large scene collections [derrod]
• Switched various internal data structures to use hash tables for lookups, resulting in significant performance and loading/saving time improvements with large scene collections [derrod]
• Exported scene collection JSON is now pretty-printed and sorted, allowing for easier tracking via git or other versioning mechanisms [derrod]
